The Reproductive System Flashcards
(22 cards)
The Site of Production of the Egg Cells (Ovum)
The Female Reproductive System
Site of Fertilization
Fallopian Tubes
Where does the production of egg cells begin?
Ovary / Ovaries
What part of the system connects the ovaries to the fallopian tubes? This part is also responsible for receiving the ovum.
Fimbriae
What is an Ovum?
Ovum is another term for Egg Cells. It is non-motile unlike Sperm Cells. It requires other cells in order to be moved or swept.
What are Fallopian Tubes?
These tubes connect the ovaries to the uterus. It is also the site of fertilization. The sperms enter the tube to fertilize the ovum (egg cell). The zygote divides from there and forms an embryo.
What happens after Fertilization? (When the sperm cells are received by the ovum)
Once the zygote has formed an embryo, the embryo travels to the uterus (womb) where the baby develops further.
The Order of Fertilization in the Female Reproductive System
Ovary - Fimbriae - Fallopian Tubes - Uterus - Vagina
It is the passage that opens to the exterior where sperm cells are also received. It is also where the baby comes out during childbirth.
Vagina
What are the two main functions of the Male Reproductive System?
First: Produce Male Reproductive Cells (Sperm Cells), Hormones, and Accessory Materials
Second: Deposit the Sperm Cells in the Female Reproductive System
In conclusion: Produce and Release
Which part of the Male Reproductive System produces the Sperm Cells?
Testis - Present outside the Abdominal Cavity in a sac-like structure called the Scrotum.
Why is the Testis located outside the Abdominal Cavity?
The formation of sperm cells require a lower temperature (35 degrees) compared to the temperature inside the abdominal cavity or the normal body temperature (37 degrees).
What is the hormone that the testis produces and what does it do?
Testosterone - It is a male reproductive hormone which regulates the formation of sperms and it is also responsible for the development of secondary sexual characteristics during puberty.
Which organ of the Male Reproductive System is responsible for producing the liquid secretions that are necessary to help the sperms get delivered?
Prostate Gland and Seminal Vesicles - These two secrete certain fluid secretions that provide nutrients to the sperm cells.
Journey of the Sperm Cells
Testis - Epididymis - Cowper’s Gland - Prostate Gland - Seminal Vesicle - Vas Deferens - Urethra - Penis
How do sperms get deposited into the Female Reproductive System?
The sperm from Vas Deferens enters another duct called the Urethra which is surrounded and supported by a muscular organ called Penis.
The system is designed to transport the ova to the site of fertilization. The fertilization of an egg by a sperm normally occurs in the fallopian tubes.
In conception, the fertilized egg is implanted into the walls of the uterus, beginning the initial stages of pregnancy.
The Female Reproductive System
What happens if fertilization does not occur?
The Menstrual Cycle or Menstruation
What happens during Menstruation?
It can last for about 3-5 days, sometimes a whole week. The lining of the uterus that supports the fertilized egg dissolves and comes out of the vagina along with other tissues where there is no embryo to support. When the woman is not pregnant, the egg will also dissolve and the cycle restarts.
A _____ _____ is a physiological regulation system in a living body that works to return the body to its normal internal state, commonly known as homeostasis.
Feedback Mechanism
A ______ feedback mechanism is noticed during childbirth, which is caused by the baby pressing against the ovary wall. The brain receives the pushing feeling via several nerves, and the pituitary is stimulated to generate oxytocin in response. The oxytocin feedback loop is responsible for uterine muscle contractions, which cause the fetus to come closer to the cervix, thereby increasing the stimulation. Until the baby is born, the _____ feedback loop continues.
Positive Feedback: Initiate (or accelerate) a Processing
A feedback that inhibit (or slow down) a process
Negative Feedback
